I'm in the process of creating a new template for our office , so far we used the Architectural Template that come with Revit. And I like that has only two phases (New and Existing) . However I opened the construction template that comes with revit and I found at least 6 phase setup. And I would appreciate it if someone of experts here tells me what is the best way to handle phases? How many phases should I setup. We do a lot of renovation projects , so we always have existing and new elements.
